How to Find and Fix Hot and Cold Spots

July 06, 2017

If you realize that you have hot and cold spots through your Genoa home, you’re not alone. This is a pretty common problem. While it might seem like a major issue, the good news is that the typical causes of hot and cold spots are typically easy to fix with a straightforward air conditioning service. The most common causes for hot and cold spots are:

  • Zero zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inefficiently insulated air ducts
  • HVAC equipment that is too big or too small

Lack of Zoning or Improper Zoning
A zoning system splits your home into separate areas, known as “zones,” and means you can set the air temperature in each zone. The system is composed of multiple thermostats that operate dampers within the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their specific zone, then open or close the dampers according to the thermostat's settings. This could be the key to keeping that one frozen bedroom warm in the winter, or that heat chamber sunroom comfortable all summer. Plus, when it’s used with a programmable thermostat, zoning may mean home energy savings of up to 35 percent.*

Poorly Designed or Ineffectively Sized Duct Systems
Some homeowners experience hot and cold spots simply because their home’s duct system is not sized appropriately for the space that needs heated and cooled, or it’s improperly designed. We find this is pretty common in homes that were built before many of today’s tools and training were around. Unfortunately, even the most energy-efficient HVAC equipment can’t live up to homeowners’ expectations if the duct system isn’t allowing it to do its job. In fact, a bad duct system could actually cause new equipment to work harder than needed and shorten its life. The pros at Assured Appliance and Heating & Air can help you decide if your duct work is working for your home.

Leaky or Inadequately Insulated Air Ducts
Even if your duct system is designed and sized properly for your home, it may still be the source of your home’s hot and cold spots. It’s common for the ducts in a home to become leaky over time. Experts like Assured Appliance and Heating & Air can inspect your ducts and let you know if they should be sealed. They might also find that your ducts aren’t leaking, but they’re not correctly insulated. Fortunately, this is also a generally easy fix.

Improperly Sized HVAC Equipment
So there’s a chance your air duct system is just fine and you have a good zoning system, but you’re still noticing hot and cold spots around your home. Improperly sized HVAC equipment may be the culprit. A system that is too small has to work harder to heat or cool your home, leaving you with hot and cold spots because it can’t take care of the amount of space it needs to condition. Even a system that’s too big can mean problems because it’ll cycle on and off too often to do its job properly.
